RE: How to stop the whole system gracefully ?

Anyone can help me ?

My system is installed using kola-ansible. The database was inconsistent due to the last unexpected shutdown, and the system could not start normally, which was very troublesome. I would like to ask what command should be used to shut down the entire system gracefully in an emergency ? Thanks.
